Question

这就是我要做的事情：

为以下main（）调用的方法定义存根。每个存根应打印＆＃34; FIXME：完成methodName（）＆＃34;后面跟一个换行符，应该返回-1。

示例输出：

FIXME: Finish getUserNum()

FIXME: Finish getUserNum()

FIXME: Finish computeAvg()

Avg: -1

这是我的代码：

import java.util.Scanner;

public class MthdStubsStatistics {

    public static int methodName (int userNum1, int userNum2, int computerAvg) {
        System.out.println("FIXME: Finish getUserNum()");
        System.out.println("FIXME: Finish getUserNum()");
        System.out.println("FIXME: Finish computerAvg()");
        System.out.println("Avg: -1");

        return 0;

    }

    public static void main() {
        int userNum1 = 0;
        int userNum2 = 0;
        int avgResult = 0;

        userNum1 = getUserNum();
        userNum2 = getUserNum();

        avgResult = computeAvg(userNum1, userNum2);

        System.out.println("Avg: " + avgResult);

        return;
    }
}

我以为我理解了方法存根，但我觉得我犯了一个非常愚蠢和简单的错误？我只能编辑代码的public static int methodName部分。

Answer 1

这种意义上的方法存根是一种没有实质内容的方法，即它没有按照预期的方式进行。您的if let urlString = NSBundle.mainBundle().pathForResource("MyFramework", ofType: "framework", inDirectory: "Frameworks") { let bundle = (NSBundle(URL: NSURL(fileURLWithPath: urlString))) let sb = UIStoryboard(name: "Main", bundle: bundle) let vc = sb.instantiateViewControllerWithIdentifier("vc") self.showViewController(vc, sender: nil) }方法应返回用户的唯一ID，而是定义一个只在每次调用时返回getUserNum()的存根。

您可以通过-1方法判断，您应该定义这两种方法：

main()

所以，定义它们。这是userNum1 = getUserNum(); avgResult = computeAvg(userNum1, userNum2);存根的样子。

getUserNum()

我会将public static int getUserNum() { System.out.println("FIXME: Finish getUserNum()"); return -1; }留给OP。

Answer 2

import java.util.Scanner;
     公共类MthdStubsStatistics {

/ *你的解决方案就在这里* /
    public static int getUserNum（）{   System.out.println（“FIXME：完成getUserNum（）”）;
     返回-1;
    }
  public static int computeAvg（int userNum1，int userNum2）{   int avgResult =（userNum1 + userNum2）/ 2;   System.out.println（“FIXME：Finish computeAvg（）”）;   返回-1;
    }     public static void main（）{   int userNum1 = 0;   int userNum2 = 0;   int avgResult = 0;

userNum1 = getUserNum（）;   userNum2 = getUserNum（）;

avgResult = computeAvg（userNum1，userNum2）;

System.out.println（“Avg：”+ avgResult）;

返回;
    }     }

Answer 3

import java.util.Scanner;

public class MthdStubsStatistics {

   public static int getUserNum() {
      System.out.println("FIXME: Finish getUserNum()");
      return -1;
   }  

   public static int computeAvg(int userNum1, int userNum2) {
        System.out.println("FIXME: Finish computeAvg()");
        return -1;
   }

   public static void main(String [] args) {
      int userNum1;
      int userNum2;
      int avgResult;

      userNum1 = getUserNum();
      userNum2 = getUserNum();

      avgResult = computeAvg(userNum1, userNum2);

      System.out.println("Avg: " + avgResult);
   }
}

Answer 4

import java.util.Scanner;

public class MthdStubsStatistics {
   
   public static int getUserNum() {
      System.out.println("FIXME: Finish getUserNum()");
      return -1;
   }

   
   public static int computeAvg(int a, int b) {
      System.out.println("FIXME: Finish computeAvg()");
      return -1;
   }

   public static void main(String [] args) {
      int userNum1;
      int userNum2;
      int avgResult;

      userNum1 = getUserNum();
      userNum2 = getUserNum();

      avgResult = computeAvg(userNum1, userNum2);

      System.out.println("Avg: " + avgResult);
   }
}

export default const workspace = new class Workspace {
    // ...constructor (if desired), properties, and methods...
}();
